Margie has 5 times as many nickels as quarters. She has a total of $2.00.

Part (a) Write a system of equations to represent the situation. Let n represent the number of nickels and q represent the number of quarters.

Part (b) Solve the system you wrote in part (a). Show your work.

Part (c) Interpret your solution in the context of the problem.


P.S. Sorry for asking so many questions, I swear this will be the last one for a while.

The only thing I really need help with is Part A, writing the equations.

Answers

Answer 1

Answer:

5n + 25q = 200 - - - (1)

n = 5q - - - (2)

q = 40

n = 5(40) = 200

Step-by-step explanation:

Number of Nickels = n

Number of Quarters = q

$2.00 = $2 * 100 = 200 cent

Nickel = 5 cent

Quarter = 25 cent

5n + 25q = 200 - - - (1)

n = 5q - - - (2)

5(5q) + 25q = 200

25q + 25q = 200

50q = 200

q = 200/5

q = 40

n = 5(40) = 200

Ok so basically if an input (x) has more than one output (y) it is NOT a function. One output having more than one input is okay though.

So G) is a function, bc for every x there is just 1 y

H) is not a function

I) is not a function either

PA HELP plssssssss ​

Answers

Answer:

50y + 75x ≥ 1000 ;

50(15) ≥ 750;

x ≥ 4

y ≥ 15

Step-by-step explanation:

Given that :

Number of stickers sold = y

Cost of sticker = 50

Cost of bag tag = 75

Number of bag tags sold = x

Total worth of items sold ≥ 1000

1)

50y + 75x ≥ 1000

2.)

To make atleast 15 stickers

y ≥ 15

Atleast 15 stickers :

50(15) ≥ 750

3.)

A possible solution :

50(15) + 75(x) ≥ 1000

750 + 75x ≥ 1000

75x ≥ 250

x ≥ 3.33

x ≥ 4

y ≥ 15

we should beat it in mind that, the greater the angle that a side of a triangle faces, the greater its length will be relatively

as we can see, the side NM faces the greater angle of 83, relative to the side LN that faces the angle of 56;

So we can conclude that;

A website received 2500 registered members in July. And the number of registered members in August decreased to 2245. What was the percentage decrease in the number of registered members?

Answers

Number of registrations a website received during July = 2500

Number of registrations a website received during August = 2245

Number by which the registrations decreased :

[tex] =\tt 2500 - 2245[/tex]

[tex] =\tt 255[/tex]

Thus, the registrations decreased by 255.

Let x be the perrcentage of decrease.

Which means :

[tex] =\tt 255 = \frac{x}{100} \: of \: 2500[/tex]

[tex] = \tt255 = \frac{x \times 2500}{100} [/tex]

[tex] =\tt 255 = \frac{2500x}{100} [/tex]

[tex] = \tt255 \times 100 = 2500x[/tex]

[tex] = \tt25500 = 2500x[/tex]

[tex] =\tt \frac{25000}{2500} = x[/tex]

[tex]\color{plum} =\tt \bold{10.2\%}[/tex]

▪︎Thus, the percentage of decrease in the number of registered members = 10.2%

x=10/3 x=10,y=30/3 x=30.y=10/3

Answers

Answer:

Use the fact that sin(x) = opp/hyp and tan(x) = opp/adj

where opp=opposite, hyp=hypotenuse, adj=adjacent and recall sin(30)=1/2 and tan(30) = 1/sqrt(3)

sin(30) = 1/2 = 17/y

y = 17(2) = 34

tan(30) = 1/sqrt(3) = 17/x  

x = 17sqrt(3)

So the answer is (d)

Note that you could have also use the Pythagorean theorem to find x instead of using tan(30).

create a polynomial in the form ax^3+bx^2+cx=0 that has solutions of x=0,x=-5 and x=11, where a=3

Answers

3x^3-18x^2-165x=0

Since we are given the solutions, we can rewrite them.

x=-5 is (x+5)

x=11 is (x-11)

x=0 is just x

Now we can write our equation:

3x(x+5)(x-11)=0

*3 comes from the a being 3

Now we multiply, I’d recommend starting by using FOIL on the last two first and getting;

3x(x^2-6x-55)=0

Then distribute the 3x:

3x^3-18x^2-165x=0

No; a range value has two domain values.

Answers

Answer:

Yes; there is only one range value for each domain value.

Step-by-step explanation:

For a relation to be a function, every input, x-value, needs to have a unique output, y-value. This means that one x-value cannot have multiple y-values. So, in a function x-values will never repeat. Since x-values do not repeat in this relation, it is a function.
